'To all whom it may concern:

Be it known that I, JOSEPH P. CLEAL, a citizen of the United States,residing at Toronto, county 'of York, Province of Ontario, Canada, haveinvented a certain new and useful Improvement in Cash-Registers, anddeclare the following to be a full, clear, and exact description of thesame, such as will enable others skilled in the art to which it pertainsto make and use the same, reference being had to the accompanyingdrawings, which form a part of this specification.

This invention relates to cash registers and has for its object theseveral improvements as are more fully described in the hereinfollowingdescription.

Fig. 30 is a view of the opening for the key thatunlocks the turn to zero mechanism.

The register held by a suitable frame and properly incased has keys, theends of which project through the case, and are provided withcharacter-bearing finger tablets. Within the case is a frame Asustaining a key shaft 10, a cam shaft 20, a shaft 40 upon which ismounted a split tubular oscillating member which has several functions,an indicator supporter 30, a fixed bar E, a segment supporting shaft 50and other shafts and bars which will be hereinafter described when theiruse is referred to. The keys are arranged in divisions and there are asmany divisions as there are differentunits of value. In one division,which will be called the first division, are nine keys, each of which isemployed to register and to indicate value from 1 to 9 cents inclusive.In the second division are nine keys, each of which is employed toindicate values from 10 cents to 90 cents inclusive. In the thirddivision are nine keys, each of which is employed to indicate valuesfrom $1.00 to $9.00 inclusive.

In the fourth division there are several 5 keys, most of which arespecial keys and are used to make indications and registrations ofspecial acts. In this division there may be, and preferably is, two ormore keys to indicate values of $10.00, $20,00 and perhaps $30.00. Thedivision of the register is shown on Fig. l by the wide spacing betweenkeys at the rear and nearends of the several lock bars 32. The keys arequite similar in construction, although not identical in form, as eachkey of a division is shaped to produce its own proper indication andtherefore differs slightly from the other keys in the division,but anunderstanding of the construction and action of the entire machine willbe evident from an explanation and understanding of a few only of thekeys.

In Figs. 7 and 8 the key marked 20$ may be taken as arepresentative ofthe value keys, and the key in front of it marked Sp is one of thespecial keys. With each value key is a companionle'ver pivoted on thesame .bar and extending to the rear of the bar 10, but not to thefront."v The key has a rearward extendingindicator-lifting point 21; thecompanion leverlacks the indicator-lifting extension but-hasa shortextension -which contactsa s'troke limitbar C on the' rear of the frame.The companion levers need not be used with thelowestvalue key "I'o'feach division, as a deep notch 29 or -rather high walls at the contactpoint 'preventsoverthrow. *(See'one cent-key Fig. .9).

[Apia 2 projects from'thejsideof the main ---='key- '20$ and engagesljthrough a slot 2 in. j 1 1 Companion"lever 2 the slot allows thecompanion lever-"to laglbehind the main key onathe return stroke; thetwo rise together. his results in holding'the rack 33 from beginning its'return oscillation until after the hasfmade enough of its return stroketo iis'c'onnect the rack and pinion. The key [203 "provided-with aforward extending projection 3 that engages through a slot in the wallsof an osciIlEtingpart-cylinder 4 on haft 40; this part-cylinder performsthe unctionof'a key coupler to couple and comel"the-contemporaneousaction of the keys 3 7 f'of different divisions and also acts as a ystop toprevent the subsequent action of any otherkeys than those whichhave been engaged to the coupler, requiring all coupled keys to performtheir full action, and return to their normalv position, in which normalposition they are entirely out of engagement with the coupler 4.

The placing of the projection upon the key and the slot for thereception of the key projection on the key coupler is a distinctimprovement over registers heretofore con structed. The projection 3 ison the rear arm of the key and the least oscillation of the key movesthe projection, which lies directly in front of the slot, across thecircle of travel of the coupler. The tubular form of the key-couplerallows the projections 3 to lie very close to the coupler so that whenone is actuated it may enter the slot and start the key coupler in aminimum period. As soon as the key coupler is started the edge 4 comesup above the beveled face of the projection 3 so as to lock out anyother keys that may be subsequently actuated. The simultaneous pressingof more than two keys from one bank is prevented by the hanger stops 7(shown in Fig. 13 and described in the next paragraph) on the back ofthe machine. The quick lock-out eifected by my slotted key coupler andprojection on the key arrangement makes the use of these disks insteadof the long hangers possible, as it is necessary for the disk hangers tofunction only at the very beginning of the oscillation of the keycoupler. In the key couplers of the prior art the key has been obligedto travel some little distance before it would actuate the key couplerto make it act as a look-out for the other keys, and it has often beenpossible to snap in a key from the same bank, causing, of course,serious trouble in registering, as keys from the same bank look into thesame registering mechanism but are calculated to move it differentdistances. Another advantage of the tubu- -lar form of key coupler isthat it makes a revolution rack (hereinafter to be described) is aboutto trip, then one of the keys can be forced to continue its movementwhile the other key is forced back; this springs the key coupler andforces one end of it so as to caus the revolution rack to convert theoscillatory movement into a full rotary movement of the cam shaft; butthe key at the opposite end of the machine has been prevented from goingits prescribed distance and hence has not completely registered so thatan amount can be held out. Still another advantage in 'this form of keycoupler is that the point of contact of the key in actuating the keycoupler is brought closer to the center of motion of the key coupleritself, which makes an easier working device and the key coupler lessliable to rebound.

The rear extensions of all keys of the register engage through agrid-like member which extends along the register at the rear and isprovided with vertical bars 0, as seen in Fig. 13; the .bars 6 serve asguides for the rear of the keys and sustain the key stops which consistof hanging disks 7 each of which is capable of a short oscillation onits supporting pin 7 except, however, a disk 7 b at each end of adivision (of 9 keys). The disk 7 b is made fast and is cut away untilits vertical edges correspond with the vertical edges of the grid-bars6, and it now serves to limit the oscillation of the stops 7. Each ofthe hanging and oscillating'disks 7 overhangs the edges of the bar towhich it is secured and touches the adjacent hanger at either side. Inan entire division there is a space between the fixed blocks which isgreater than the added Width of the hangers by the thickness of one key.The end 21 of the key 20$ (or the similar end of any. key,

either special key or value key), projects throughthe grid and in itsnormal position rests at the bottom of the grid below the key stop 7. Assoon as any one of the keys is actuated to lift the rear end thereofsufficiently high 'to contact the disk above it,- the two disks, one ateach side, swing to permit the key to pass through between the twodisks, and-when any key is in a position'to fully contact the two disksof these two guide bars, the entire space between the fixed blocks 7* isfilled, and while the key is in this position no other key can be-actuare in a condition to .return.

ated. As soon as the key passes above this position the key coupler stopcomes into action and prevents any other key of the entire I registerfrom being actuated. Thus, there may be coupled together and actuatedtogether any" combination of keys, provided only there-is in suchcombination only one key from each division. Y j The spring 4 (Fig. 27)put into tension by the action of the key serves to throw the keys backto their normal position, as soon as they have made their complete throwand The complete throw of the keys is insured by means of a, toothedrack 8 secured to the key coupler 4 which engages with a :tumble-overpawl 8 and compels the full oscillation of the member 4. in eitherdirection before it can start on its return motion. The pawl 8 ispivoted to any suitable part of the frame as to post B, and isheld withits point in proper position to engage the rack 8 by a light spring 8The rear extension 21j0f the key extends through the guide and projectsunder the vertical indicator rod 9 of the indicator 9. The rod 9 isprovided with a claw 9 that normally rests on the cross bar C of theframe, and, holds the indicator rod with.

. its lower end raised some distance above the which a link 11 extendstonear the front of the frame; the link is driven by a rotating cam 12(seen in Figs. 9 and 10) the link 11 connects directly to a standardlever arm 12 pivoted onthe key shaft 10 upon which the key levers arehung. The cam 12 is timed to oscillate the indicator supporter 3Oproperly to catch the claws of the lifted indicator rods in the grooveat the moment they have received their complete lifting actuation. It isalso timed to rock the indicator supporter in the opposite direction todrop the lifted indicator rods shortly after the subsequently actuatedkey has commenced to lift its proper indicator rod, so that there is aperiod of time intervening after the previously lifted indicator roddrops before the presently rising indicator rod reaches its elevatedposition and is caught in its elevated position, the time interveningdepending upon the shape given to the race in the cam 12.

The cam 12 is on the cam shaft 20 which extends from end to end of thecase and is driven in revolution by mechanism shown in Fig. 2. On theend of the key coupler 4, is a collar 14 which carries a crank pin 14(seen in Fig. 2). side of the general surface of the key coupler A onthe collar 1 1 which projects beyond the surface and at the end of thekey coupler 4 and connects with a double rack member 15 provided withtwo racks 15 and 15 one at each side of the slot which extendslongitudinally along the member. A mutilated pinion 16 mounted on thecam shaft 20 engages the racks 15 and 15 the regularly toothed part ofthe pinion engages the rack 15" on the down stroke of the key whichturns the key coupler 4 in the direction of the arrow shown in Fig. 3.The same regularly toothed part of the pinion engages the rack 15 on theup stroke. At each end of the rack member is a pin (17 at the bottomend, and, 18 at the top end), which pins engage in a notch 19 in thepinionat the time the one rack leaves the pinion and the other engageswith it. The reciproca- This pin is located outtion of the double rack15 revolves the pinion l6-co-ntinuously in one direction, and as the camshaft 20 is fixed to the center of the pinion it is revolved always inthe same direction and is given a full rotary move. ment for eachoscillation and return oscillation of the key coupler.

The value of the key actuated is trans ferred to register wheels by amechanism which is repeated in the several divisions and in eachdivision each key is special and arranged to actuate a driving rackthrough an are limited to the special value of the key; that is, the onecent key will actuate the rack which drives the register wheels adefinite distance; the two cent key will drive it twice as far and thethree cent key three times as far. This is effected by bringing theactuating part of the key lever into actuating contact with the partsconnected intimately with the driving rack at a period corresponding tothe value of the key. If the value of the key be high the contact ismade quickly; if the value of the key be low the contact is made at alater period and the contact continues through a shorter duration. Thiswill be understood by a comparison of Figs. 2 and 9. In Fig. 2 is showna key having value 9, and at the rear end of this key the companionlever is shown with a hook 25; the key has a cam face 28 which is anintegral part of the key and which engages under and lifts a lock bar 32that is a common bar actuated by the keys of a division and rocks thesegmental rack 33. The rock arm which carries the lock bar is .mountedon a segment-supporting shaft 50;

this shaft 50 is itself suspended by hangers 12 from a fixed bar E ofthe frame. During periods of rest when the keys are all in normalposition with their finger terminals lifted, the segmentsupporting shaft50 hangs with the racks 33, (of which there is one for each division ofthe register) out of mesh with the register pinions. In coming into meshwith the register pinions the lock bar changes axes of swinging, a link31 extends from the segment-supporting shaft 50 forward and engages witha cam 36 mounted on the shaft 20 which has a full revolution at eachcomplete stroke of the key. A pin 3%. projects from the link 31 into therace of cam 36 and the race and pin are timed to draw thesegment-supporting shaft 50 forward immediately after the beginning ofthe stroke of the key and this brings the segmental rack 33 intoengagement with the register pinion 37. Subsequent movement of the keylifts the lock bar 32 and oscillates the segmental rack 33 giving to therack such a degree of oscillation as is given to the lock bar 32, whichitself depends on the amount of such motion after the contact or camface 28 of the key strikes it. Each of the companion levers of a key isprovided with a hook 25 which engages over the lock bar 32 during all ofits register actuating stroke and prevents overthrow. The one cent keyand the special keys have no companion lever. The one cent key (as shownin. Fig. 10) is provided with a deep notch 29 which widens to permit thedisengagement of the segmental rack 33 and pinion 37 as will beexplained. The character of the slot used in the one cent key (also theone dime key and the 1$ key, and the 10$ key) is such as to prevent anypossible overthrow, and a companion lever is not used in connection withit or with the unit keys of any order.

Adjustment of the initial position for the segmental rack 33 is made bymeans of an adjusting screw 39 that engages through the frame bar F andis held in adjustment by jam nut 41. The link or pitman 31 actuated bythe cam 36 fixed to the cam shaft 20 draws the segment-supporting shaft50 forward and brings the segmental rack 33 into engagement with theregister pinion 37 and the segmental rack 33 being oscillated to adegree which corresponds with the value of the key that is actuatedrotates the pinion 37 correspondingly. The pinion 37 is mounted 011 acounter-supporting shaft 80 and carries on its hub a ratchet wheel 27and on the same hub is the counter wheel 201. During the pressure strokeof the finger on the key the segmental rack 33 is swung forward so as tochange axes of swinging and brought into engagement with the pinion, andthe oscillation continued until the full value of the key is registeredon the counter wheel 201. At the beginning of the return stroke the cam36 ,is positioned to first of all disengage the segmental rack 33 andthe pinion 37 by producing a back-ward swing of the hangers of thesegmental-supporting shaft 50, and neither the pinion, the ratchetWheel, nor the counter wheel makes any return movement during the returnstroke of the key, they being held by a retaining pawl 52 that engagesthe teeth of the ratchet wheel.

With the counter wheels primarily actuated by the rack 33 are associatedwheels of higher order onto which carrying is effected. There is first acounter wheel actuated by nine keys of the lower or cent order. Carryingis effected fro-m this counter wheel to the counter wheel which isactuated by the keys of the dime order, which not only acts as asecondary wheel for the first counter wheel, but acts as a primary wheelfor its own registration. This is followed by the wheel of the thirdorder, which also acts as a primary wheel for the units of the thirdorder and is actuated at the proper time by the wheel of the next loweror dime order, and following this are a number of wheels which carry thetotals to any amount desired. The carrying is accomplished properly,although several keys of different divisions have been coupled and eachhas acted on its own register during the down stroke. On Fig. 1 thecounter wheel of the first order is indicated at 51. g This is actuatedby any one of the keys in the first division between one cent and ninecents inclusive. Carrying is efiected from this wheel to wheel 51; thewheel 51 is also actuated by any one of the keys (Z to 61" inclusive.Carrying is effected from the wheel 51 to wheel 51 and as the action ofthe keys is continued the sum of the values is carried onto wheels 51and thence on to wheels 51, which are not primary wheels. The wheels 51,51, 51?, and 51, are all of them primary wheels, and the wheels 51 and51 and 51 are secondary wheels as well as primary. The means by whichthe carrying is accomplished will be best understood by an examinationof the Fi s. 15 to 19 inclusive. Connected with the pinion 37 is asingle tooth wheel. This is shown on the drawing as made on a collar 38with a single tooth 39 and in close proximity to the pinion 37. Withsome of the wheels, as with the wheel 51 it is spaced by a long collar38 from the wheel, but its action is the same whether it be in closerelation or in a more distant relation therewith. The long toothrevolves with the pin ion and once in each revolution trips an arm ofthe stepped pawl that is pivotally connected by the rod .44 to a fixedpoint of the frame as the bracket (i which extends in from the mainbody. of the frame. ()n the same pivot with the stepped pawl 22 is atransfer lever 23. The transfer lever 23 is a compound structureconsisting of a T shaped body, the stem of which is pivoted by the rod44 to the bracket Gr. One branch 24 of the transfer levers 23 isprovided with i a pin that engages in a cam race in the cam 45 on thecam shaft 20, which cam rotates once at each stroke of any key. The freeend of the transfer lever carries a transfer pawl 46 pivoted to it; theengaging end of the transfer pawl normally lies in close proximity tothe ratchet wheel 27; the pawl 46 is an actuating pawl which at timesactuates the ratchet wheel 27 and at other times oscillates withoutactuating the ratchet wheel. Its actuating action is accomplished by itsposition with respect to the upper branch of transfer lever 23; thisposition is determined by the stepped pawl. The free end of the steppedpawl is provided with a stepped catch 47, on either step of which theend of the pawl 46 may engage. The step of the pawl 47 is pressedagainst the hanging end of the transfer pawl 46 by a compression Ispring 48 and the end of the transfer pawl 35 of the transfer pawl 46held down in position to engage the tooth of the ratchet wheel 27. Therevolution of the cam shaft 20 which takes place with each actuation ofthe key now swings the end 24-of the transfer lever- 23 bringing theupper end and the transfer pawl 46 toward the ratchet wheel andactuating the ratchet wheel by the contact which now takes place betweenthe transfer pawl and the ratchet wheel. This actuating movement of thetransfer levers is effected at different times after the segmental rackshave withdrawn from the pinions and occurs with respect to each leverafter the transfer pawl has been set. The setting and actuation of eachtransfer lever is timed to take place after the setting and actuation ofthe one of next lower order.

The cam disks which actuate the last three wheels, to the left in Fig.3, which are all secondary and never primary, are fixed on a sleevewhich is on the shaft 20 and capable of revolution independently of thecam shaft 20, but compelled by the mechanism about to be described torevolve intermittently therewith, making a full revolution for each fullrevolution of the shaft, but making the latter part of the revolutionrapidly and after the shaft itself has ceased to revolve. This isnecessary to allow all the transfer pawls to be set and actuatedprogressively which could not be done in the part of the revolution ofthe cam shaft which remains to do this work. In order to provide motionafter the cam shaft has ceased to revolve the cam disks are fixed onthis sleeve 2 121 and one of the disks is provided with a pin 122extending from the side which is contacted by a pawl 123 pivotallysecured to the key shaft 10 and actuated in both directions positivelyby cam projections 124 and 125 on the key coupler 4. During a part ofthe oscillation of the key coupler 4 the cam projections engage the endsof the pawl 123, which ends are provided, with antifriction rollers 126and 126 and the stop 127 on the pawl is swung into the path of the pin122. A spring 128, one end of which. is secured to one of the disks, andthe other end of which is secured to the cam shaft 20, is wound or putunder tension by the part of the revolution of the shaft after the pin122 has contacted the stop 127 and the cam disk temporarily stops. Onthe return oscillation of the key cou ler 4 the stop is swung out of thepath 0 the pin 122 and the spring completes the revolution of the camdisk and completes the carrying movement of all the pawls of these threewheels, bringing them all into action progressively. The progressiveaction is due to the lead of one cam over another.

In addition to the registers-indicating the values of the keys there isa special register for the special keys, including in these specialregisters one set of register wheels which indicates the number of timesthat the machine itself has been operated, making a registration for thedepression of any and every key each time it is actuated, andregistration for each of the special keys indicating the number ofspecial operations that the user of the machine has performed.

The special keys are all located at the left- .will be designated as thespecial register that is placed in the second position fromthe rightend. The sleeve supporting shaft 60 is actuated by crank 61 which islinked to one of the special keys, as for instance, the special key atthe extreme left indicated on Fig. 1 as Chg and this actuates the crank61 and primary wheel of the primary set 62 of the special tally wheels.The crank 63 on hollow shaft 64 actuates a crank 63 on the opposite endof the shaft 6 1 and actuates the primary wheel of the second spe cialtally set 65 on the register. The crank 66 on hollow shaft 67 actuatesthe crank arm 66" on the opposite end of this shaft and this actuatesthe primary wheel of the third special tally set 68 on the machine. Thecrank 69 on the hollow shaft 71 actuates a crank 69, and the primarywheel of set 7 3 of the fourth special. tally set, these four specialkey connections and four special tally groups being suflicient for amachine of ordinary size. The location of the several tally sets isshown on Fig. 1, the through connection'from the special keys is shownon Fig. 26.

The set 7 3, which may be called the cus tomers tally set, is actuatedwith every action of any key of the entire machine by a pitman shown inFig. 22 and in Fig. 25, and it is thought that an understanding of theworkings of all of these special tally troups will be understood from anexplanation of the group shown in Figs. 22, 23 and 25, in which, exceptthat the initial actuation is from different sources, is found arepresentation of all of these tally groups. Considering the rock lever7 9 as substituted for the key the subsequent mechanism of each group isalike in all respects. In the one case the link 81, (Figs. 4 and 6) isconnected to and actuated by a key, and in the other case it isconnected to and actuated by a rock lever 79 (Fig. 22) which is rockedby a cam 85 on the shaft 20 that revolves with each actuation of thekey. The lever 79 is pivotally supported on shaft 180 and is providedwith an anti-friction wheel 83 which engages against the cam 85 whichrocks the pawl lever 69 with each revolution of the wheel just as inconnection with the other special groups the lever corresponding to pawllever 69 is rocked directly by the key. Thiscustomers group of tallywheels is at about the middle of the machine and the lever 69 is pivotedon the outside of the sleeve 71 shown in Fig. 26. On the specialregister wheel shaft 90 is a ratchet wheel 91 which is actuated by acompound pawl 92, the pawl 92 having three fingers 92, 92 and 92, whichengage with three consecutive ratchet wheels on the shaft 90 andutilizing what is well known as the deep notch method of carrying fromthe primary to the second and third wheels. The deep notch system ofcarrying, being in such common use and so well known, it is not thoughtnecessary to enter into a careful description of it beyond the merestatement that the pawls are actuated by a primary lever 69 and thewheels are held against reverse motion by a holding pawl 95.

The resetting mechanism is similar inboth register systems. Forresetting purposes the register wheels strung on either shaft, as forexample, each wheel strung on counter wheel shaft is provided with apawl that engages through the opening 94: in the hub and engages in anotch or long slot 96 in the shaft. This allows the counters to bepicked up when the shaft upon which they are located revolvesf Allspecial or tally groups are on the special register wheel shaft thevalue indicators are on the counter wheel shaft 80. The special registerwheel shaft 90 provided with a gear wheel 97 is con. nected to thecounter wheel shaft 80 of the total adding group of wheels by an idler98 and turned therefrom by the key which is inserted in a key-hole 99 inthe end of the counter wheel shaft 80. The counter wheel shaft 80 cannotbe turned until it has been released from the restraint of a stop 106which is actuated by the bolt of a look similar to a Yale lock. The keyinserted in key-hole 99 cannot actuate the counter wheel shaft 80 untilanother key has been previously inserted in the lock 101 and shot thebolt there and at the same time raised a flash from off the groups ofspecial register wheels and off the groups of total adder wheels. Theflash cannot be lifted without first actuating the bolt of the lock 101and after the flash has been lifted the bolt of the lock 101 cannot beretracted or the key taken out until the register wheels have been setto zero. Preferably, two keys are used, the key in 101 being caughtafter it has been used to shoot the bolt and raise the flash and notbeing removable therefrom until the resetting has been accomplished, andthe flash returned to its concealing position,

after which the key may be removed from lock 101. a

On the counter wheel shaft 80 is a segmental disk 102. In the keycoupler 4 is a notch 103 and an angled rock arm 104 provided withterminals, one of which 105 engages in the notch 103, and the other ofwhich 100 engages in front of the flat face of the disk 102, andprevents the simultaneous rotation or oscillation of both. When in theposition shown in Fig. 10 the counter wheel shaft 80 is locked againstrevolution, and the machine is in condition for its regular use. When inthe position shown in Fig. 12 the use of the machine is stoppedtemporarily and the counter Wheel shaft 80 can now be turned while thepoint 105 of the lever 104 is engaged with the key coupler 4 and nowprevents the oscillation of that member, whereas the point 106 has beenlifted from in front of the flat face of the disk 102, and the shaft 80with the disk upon it and the shaft 90 can be rotated for resettingpurposes; both of these are adapted to catch the register wheels mountedupon them at the proper point and rotate them forward to zero. On thecounter wheel shaft 80 is also a cam disk 107 with a notch 108 and astop 109 and a lever 110 is pivoted on the fixed bar E. By examining.

Fig. 11 it will be seen that the cam 107 is highest at 109 (its heightbeing shown in Fig. 10) and that its diameter "lessens as the eyetravels around the cam counterclockwise but as the eye nears theprojection 109 it is seen (Fig. 10) that the periphery of the cam isfarther from the center of the shaft 80 and as it approaches theprojection 109 it is about on the same plane as the lower edge of theprojection 109.. But just before the projection 109 is reached thesurface of the cam drops abruptly forming a notch indicated as 108 (Fig.11). The lever 110 carries a laterally projecting point 111 and the camcarries a laterally projecting point 109 which both project into acommon plane perpendicular to the axis of the shaft 80. Hence when theprojection 111 rides on the cam in the resetting operation it is thrownagainst the projection 109 and the resetting temporarily stopped untilthe projection 111 has had time to drop into the notch 108 and under theprojection 109.

The bolt 112 of the lock 101 lifts the end 100 of the rock arm 104 outof its position in front of the flat face of the disk 102 andsimultaneously interlocks the point 105 with the member 4.Simultaneously with this movement a link 113 that extends from the 105end of the arm 104 engages a rock arm 114 which swings on the counterwheel shaft 80, and which is in parallel bar arrangement with a link 115that controls the two flash aprons 116 and 117 from the flash apron '117a link 118 extends to an ordinary coun and is the flash bar of thecounter wheels.

The flash bar 116 serves to cover the special tally wheels. v

A cam 87 on the counter wheel shaft 80 on the left end thereof actuatesa link 88 to draw a bar 120 against the transfer pawls 46. If this werenot provided, the result would be that the lower end of the carryingpawl 46, would beheld so that the stepped pawl 47 would resume its setposition after it has been'forced down by the tooth 39 contacting thearm 22 as the counter unit is revolved to turn to zero, and all thecarrying pawls would be tripped and would carry one on each succeedingcounter wheel.
